Answer:
Length = 3.7416
Step-by-step explanation:
The lenght of a 3D vector is given by the formula below:
L = sqroot(x^2+y^2+z^2)
Replace the data you have in the formula and you have:
L = Sqroot(2^2 + 3^2 + 1^2)
L=3.7416
Answer:
Each angle is 60°
Step-by-step explanation:
The 2 angles are equal to each other because they're alternate exterior angles:
10x - 20 = 7x + 4
10x - 7x = 4 + 20
3x = 24
x = 8
10x - 20
10(8) - 20
80 - 20
60
Since these angles are exterior angles, their angle measures are equal so they both are 60°
Step-by-step explanation:
Swap x and y.
Solve for y.
So the inverse is
